Local knowledge
How Greenwich properties leak
Greenwich housing is dominated by period conversions, post-war estates and new riverside towers. New riverside developments run plastic push-fit pipework in ceiling voids; a single failed O-ring can soak several flats before it surfaces.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest — before we arrive.
Covered in Greenwich
- Hidden leaks under floors and in walls
- Underground supply pipe leaks
- Central heating and boiler pressure loss
- Underfloor heating loop leaks
- Flat-to-flat leak origin investigations
- Trace & access reports for insurance claims
Three methods, one marked point
Acoustic survey
Ground microphones and correlators follow the sound of escaping water through floors and ground.
Thermal imaging
Infrared cameras reveal wet patches and buried heating runs through the floor surface.
Tracer gas
A safe hydrogen mix escapes through the exact failure point and rises to our surface detector.
What fails here
Common leak problems in Greenwich
01
Push-fit joint failures in riverside tower voids
The new blocks along the Greenwich and Woolwich waterfront run plastic push-fit pipework through ceiling voids and risers. A single perished O-ring or a pipe that was never fully seated at the collar can weep for weeks, tracking along the void before it drops through a light fitting two flats down. We use thermal imaging and acoustic tracing to find the failed joint without opening every ceiling, then produce an insurer-ready trace and access report for the building management team.
02
Leaks under solid and screeded floors
Much of Greenwich has heating buried in solid floors, from 1930s Eltham semis to modern screeded slabs with wet underfloor loops. A pinhole in a buried circuit shows only as a warm patch, a dropping boiler pressure, or a slow rise in the water bill. We trace the run with thermal and acoustic equipment and pinpoint the leak to a small area, so any lifting of tiles or screed is kept to the one spot that matters.
03
Hidden leaks in Victorian and Georgian period pipework
Older Greenwich, Charlton and Blackheath homes hide lead, iron and early copper runs behind lath-and-plaster and under suspended floors that have been boxed in over decades. Damp on a chimney breast or a stain spreading across a cornice rarely sits under the visible mark. Non-invasive detection lets us follow the water back to its source and confirm the leak before any panelling or plaster is disturbed.
04
Flat roof and parapet ingress mistaken for plumbing
Warehouse conversions, mansard extensions and flat-roofed rear returns across the borough let rainwater in at failed felt laps, cracked parapets and blocked outlets. The damp often appears near a bathroom or kitchen and gets blamed on a pipe. We separate rainwater ingress from plumbing leaks using moisture mapping and, where needed, a controlled trace, so you are not paying to chase a pipe that is sound.
From the forums
What Greenwich residents say about tracing hidden leaks
Across r/HousingUK, r/DIYUK and MoneySavingExpert, Greenwich threads tend to cluster around two housing types. Owners in the Royal Arsenal Riverside and Woolwich new-builds describe push-fit joints failing inside floor voids and risers, with water tracking down and soaking the flat below before anyone spots a stain. Much of the frustration is not the leak itself but the who-pays dispute between leaseholders, the freeholder and building management, plus the wait for access to shared risers. Owners of Georgian townhouses near the town centre and 1930s Eltham semis more often report slow losses in old concealed pipework. A recurring theme is that people want the source pinpointed and documented before they open a ceiling or file a claim.

How to Choose a Leak Detection Company in London (Without Getting Burned)
A plain-English buyer's guide to hiring a leak detection firm in London: why cheap hourly rates backfire, what real equipment looks like, how to read no-find-no-fee small print, and who is actually responsible for the pipe.
Leak detection in Greenwich — FAQs
How quickly can you attend a leak in Greenwich?
Same-day appointments are usually available in Greenwich, and next-day almost always. If water is actively escaping, tell us when you book — live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No. Every detection visit in Greenwich is covered by our no find, no fee promise: if we attend a confirmed live leak and cannot locate it, the detection fee is waived.
Can you provide a report for my insurer?
Yes — trace and access reports documenting the cause, precise origin and affected areas are available for every Greenwich detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Greenwich do you cover?
All of it — including Greenwich, Woolwich, Eltham, Charlton, Blackheath. We cover every London borough, so coverage never depends on which side of a postcode line you live.
A leak from the flat above is soaking my Royal Arsenal Riverside flat. Who is responsible?
Responsibility usually depends on where the leak originates and what your lease says, so it often becomes a dispute between the upstairs leaseholder, the freeholder and building management. A neutral leak-detection survey that pinpoints and documents the source helps everyone agree who should act and supports an insurance claim. We provide an insurer-ready report; we do not decide liability.
Can you find a leak in a period Greenwich townhouse or 1930s Eltham semi without damaging finishes?
Yes. In older concealed pipework we use non-invasive methods such as acoustic listening, thermal imaging and moisture readings to narrow the source before anything is opened up. This limits disruption to original plaster, cornicing and floors. You receive a written report showing where the leak is, typically for a fixed fee of £250 to £450 depending on access and property size.
